Close Complex Open Mesh for 3D Print

[Jillian_Aleah_Marie (Jillian Aleah Marie Manzanilla Villegas)]

I need to boolean difference a mesh and then print it, but MeshBooleanDifference doesn’t work because it is an open mesh. I’ve tried remeshing, filling the holes, and converting to subd, but nothing has worked. Does anyone know how I can make this a closed mesh?

If possible you must try shrinkwrap in Rhino 8 WIP

Rhino 8 Feature: ShrinkWrap

ShrinkWrap lets you create a wrapped mesh from mesh, NURBS geometry, SubD, and Point Clouds. Just about anything! ShrinkWrap meshes are ideal for creating: Meshes for 3D printing. A solid union mesh from multiple input objects. A solid mesh from 3D scan data fragments. Meshes without internal self intersections. Offset meshes for shell operations Reverse engineering workflows Point cloud meshes Valid closed meshes from broken or often hard to repair geometry. [0648] [ShrinkWrap] …

How did you manage to have such an awful mesh ?

Here a mesh that was healed with Dendro in Grasshopper.
I think you mesh has many problem, it is very far from the origin. And perhaps the scale. So I put the center near the origin ans made a 1000 scale.
With Dendro just use the mesh to volume component with a good voxel size. I choose 1 for the scaled mesh. It is more fast than Shrinkwrap!

Thanks so much, this worked! :))))
